Comtech MCDD-100 Detecting Device

Overview
The MetaCarrier® Carrier Identification detecting device, the (MCDD-100) builds on our leadership in providing equipment to optimize the quality of satellite links. The MCDD-100 is used to detect the Carrier Identification (CID) of a host carrier that has embedded the DVB-CID ETSI TS 103 129 standards-based Carrier ID technology. DVB-CID ETSI TS 103 129 uses spread spectrum technology at very low signal levels to enable identification of host carriers. The MCDD-100 is compliant to the DVB-CID ETSI TS 103 129 standard for combating satellite interference and is based on Comtech’s award-winning MetaCarrier technology.
Satellite interference has a significant financial impact on both satellite operators and end users. Comtech EF Data developed the MetaCarrier technology to address this industry-wide challenge. This new standard will directly benefit users and operators in the avoidance of accidental interference. MetaCarrier technology works by embedding and detecting a small message and unique ID within a video or data satellite carrier.
Modulators supporting DVB-CID ETSI TS 103 129 embed the information using a low-speed data sequence containing information
about the transmission carrier and spread this sequence using Direct Sequence Spread Spectrum (DSSS). This spread spectrum
carrier is then combined with the transmission carrier to produce a composite carrier with the transmitted video or data and an
embedded CID. The embedded CID significantly reduce the time to identify and clear interference sources. This technique does not
add appreciable noise or power to the host carrier. The robust spread spectrum signal enables the transmission carrier to be identified
even when the transmission carrier is well below another carrier or near the noise floor itself because of interference.
The MCDD-100 is used to decode an embedded unique carrier identification sequence for a host carrier. In an interference situation,
the MCDD-100 may be used to decode the CID of an interfering carrier that may not be part of one’s own transmission network, as long
as the interfering carrier has an embedded CID. The MCDD-100 can operate in both non-interfered and interfered conditions, and is
ideally suited for SCPC, MCPC and video satellite carrier transmissions.

Features

• Can detect multiple carriers per transponder and resolve their MetaCarriers via external center frequency and bandwidth input
• Remote control via Ethernet management
• Can be commanded via SNMP by an external carrier monitoring system
